I wholeheartedley agree with your viewpoint
They do heat the water in the separate learning pool (not the linked one) to a higher temperature than the main pool but in my experience they sometimes cock it up - so I've taken my toddler for lessons and she's been fine one day and then really really cold another day. In fact I did go out and buy a wetsuit for her after a particularly bad swim there one day. I don't think it should be that hard to get it consistently right and as it's completely separate from the main pool it shouldn't affect the temperature in there. I've been to plenty of other pools (Crystal Palace, Downham, Sydenham) where they have two pools in the same room and managed to heat them both appropriately.
True, but 2 lots of lessons go on in the linked pool too which I guess has to be the same temperature as the main pool and so is often too cold for kids.
